Before you install a new furnace or before you convert to a gas appliance, you should be sure that all areas are thoroughly inspected and cleaned. Your technician will insure that your new unit is safe to be installed into an existing setup. Likewise, if you are shopping for a new home, you should schedule a furnace inspection and/or cleaning. Even if you have an existing unit with no changes to the system, we recommend an inspection and cleaning before cold-weather season.
